Now that 2012 is here, the last thing you want is your attire to be considered "so last year."

Which is why we're turning to these three stars and their statement-making getups for ideas on what to rock this season.

1. Plunging Neckline
Although Rihanna opts to show off her assets by going braless in a sheer dress, Lea Michele went the more tasteful route of putting hers on display in Los Angeles December 5, when she dazzled in a cleavage-baring Valentino gown at the New Year's Eve premiere.

2. Keyhole Cutout
At the CFDA/Vogue Fashion Fund Awards in NYC November 14, Olivia Wilde demonstrated another appropriate way to show some skin -- in a short flouncy Cushnie et Ochs dress with a diamond-shaped cutout on the chest.

3. Skintight White
Following in the style footsteps of Kate Winslet and Jessica Biel, who both wore memorable form-fitting white dresses in 2011, Kim Kardashian showed off her famous curves in a curve-hugging mini by Gucci that featured a keyhole cutout and an embellished neckline in Las Vegas December 31.
